반응 단계
A solution of 4-(3-ethynylphenylamino)-7-methoxyquinazolin-6-ol (2.9 g, 0.01 mol), 2-methoxyethyl methane sulfonate (4.6 g, 0.03 mol, 3 equiv), and cesium carbonate (9.9 g, 0.03 mol, 3 equiv) in DMF (100 ml) was heated to 60° C. for 12 hours. The reaction mixture was cooled to room temperature and poured into cold water, the solid was filtrated and dried to give 1.5 g product. MS (ESI) m/z: 350 (M+1).
